DAC7632VFBTG4

Digital To Analog Converters Overview

The DAC7632VFBTG4 is a dual-channel, 16-bit voltage-output digital-to-analog converter manufactured by Texas Instruments. It utilizes an R-2R resistor string architecture to provide high-resolution analog signals from serial digital inputs. The device features buffered voltage outputs capable of driving loads directly without external amplification in many applications. It operates with a single +5V analog supply and a separate digital supply, supporting standard SPI-compatible interfaces. The component is housed in a 28-pin SOIC package and is designed for industrial environments with a specified operating temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Dual independent 16-bit channels providing precise voltage conversion
• Integrated output buffers eliminate the need for external operational amplifiers
• Serial interface compatible with standard DSP and microcontroller protocols
• Power-down mode reduces current consumption during idle periods

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Programmable power supplies and battery test equipment
• Data acquisition systems with analog output capabilities
• Medical instrumentation requiring stable reference voltages

Digital To Analog Converters Procurement Notes

Verify the suffix 'G4' confirms RoHS compliance and lead-free manufacturing status as per Texas Instruments standards. Confirm the package type matches the required PCB footprint, specifically the 28-pin narrow SOIC variant. Check for any specific revision notes in the latest datasheet regarding pin compatibility or electrical parameter updates compared to earlier production lots.

Digital To Analog Converters Selection Notes

Select this component when dual-channel 16-bit resolution is required with integrated buffering. Compare settling time and linearity specifications against system requirements. Ensure the SPI interface timing aligns with the host controller's maximum clock speed. Consider thermal dissipation if multiple units are placed closely on the board within the industrial temperature range.

Digital To Analog Converters Part Context

This part belongs to the DAC763x family of 16-bit voltage-output DACs from Texas Instruments. It shares architectural similarities with the DAC7631 (single channel) and DAC7642 (dual channel). The VFBTG4 designation indicates the specific package, temperature grade, and environmental compliance. It serves as a direct replacement for older non-RoHS versions like the DAC7632VFBT in new designs.

Digital To Analog Converters Replacement Considerations

The DAC7632VFBT is a functional predecessor but lacks RoHS compliance. The DAC7642 offers similar performance in a different package. Verify pinout compatibility before substituting with other 16-bit dual DACs from different manufacturers.
